Title: Improvements in or relating to means for the manufacture, centrifugally, of pipes, columns and other articles
IPC: B28B21/30
Filed: 1925-12-24
Abstract: 257,882. Moir, D., and Buchanan, H. Sept. 2, 1925, [Convention date]. Centrifugal machines.-Relates to apparatus for making or lining with plastic material pipes or other hollow bodies under the centrifugal action caused by the free rolling of the mould or pipe from one position to another along a rail track. According to the invention, in order to make the rolling uniform and to prevent derailment, speed compensating members coaxial with the mould, pipes or the like are employed, such members comprising rollers of varying cross-sectional dimensions arranged to act in opposition. In the arrangement shown in Fig. 1 for lining a pipe of large diameter having turned and bored spigot and socket ends, a Mannesman supporting tube 1 is passed through the pipe. A sleeve 3 with a tapering outer surface is fixed to one end of the tube 1 and a similar sleeve 4 is slidably mounted on the other end, the conical surfaces being adapted to run on rails 2. The spigot end of the pipe fits a flanged disc 7 while the socket end is borne by second disc 10, the discs being bored centrally to suit conical or equivalently tapered seatings 11 on the sleeves. The parts are held tightly in position by screwing up a nut 14 on a stud 12 firmly fixed in the tube 1, an end washer 13 being placed between the nut and the sleeve 4. During rolling any tendency towards derail. ment is arrested by the taper of the sleeves 3, 4. In a modification the edges of the discs 7, 10 are alike and shaped to engage the internal circular edges of the pipe. In the case of smaller pipes 18, Fig. 3, two conical split sleeves 16, 17 are clamped on the pipe by means of bolts passing through lugs 19.

Patent GB-653298-A (GB)
Title: Pulse code modulation system
IPC: H03M1/00
Filed: 1948-12-17
Abstract: 653,298. Cathode-ray tubes. STANDARD TELEPHONES & CABLES, Ltd. Dec. 17, 1948, No. 32697. Convention date, Feb. 26. [Class 39 (i)] [Also in Group XL (c)] Relates to the construction of a cathode-ray tube for converting amplitude-modulated pulses into groups of code pulses (see Group XL (c)). A train of amplitude-modulated pulses is passed through a mixer circuit 4, Fig. 1, and push-pull amplifier 5 to the horizontal deflection plates 6, 7 of a cathode-ray tube 8. A line type beam 33, Fig. 2, is thereby deflected across a number of coding bars 12 and a beam centring bar 13 simultaneously. The no-signal position of the beam 33 is in the centre of the coding bars which have portions 35, Fig. 3, of low secondary emission etched and filled with colloidal carbon, separated by code pulse producing portions 34 of high secondary emission. A positive electrode 11 collects the secondary electron emission. Each collector bar 12 is connected through an individual translating circuit 14 and  gating circuit 16 to a mixer circuit 15. The gating circuits are supplied with pulses from generator 3 and introduce different delays to produce the correct succession of code pulses in circuit 15. The input amplitude modulated pulses are quantized by making the beam width slightly narrower than the minimum distance between sensitive regions on the code bars 12. The ungated outputs of all the bars are mixed in circuit 19 and fed through amplifier 20 and keying circuit 21, controlled by generator 3, to a flip-flop circuit 22. When the beam is deflected to such a position that it impinges entirely on insensitive bar portions the flip-flop circuit 22 operates to add or subtract a small increment of voltage to the pulse in mixer 4 to deflect the beam on to the adjacent code pulse bar portions. For centring the beam, the two portions 37, 38 of the bar 13 are connected to twin amplifiers 23, the outputs of which after rectification in circuit 24 are applied through a push-pull amplifier 25 and manual centring control 26 to the horizontal deflection plates 6, 7. If both the portions 37, 38 receive the same number of beam excursions, the in-phase equal voltages applied to amplifier 5 produce no output. Otherwise, a difference in output from the two portions is amplified and applied to the deflection plates 6, 7 to bring the beam back on centre. Specification 644,936 is referred to.

Title: Improvements in or relating to methods and means for forming ribbon composed of separable extruded rubber threads
Inventor: GUAY LEONARD
IPC: B29D99/00
Filed: 1961-09-18
Abstract: <PICT:0917768/IV(a)/1> A tape or ribbon of rubber is made by extruding several latex threads, washing and then drying and partially curing the threads in an oven.  The partially cured threads are coated completely with dry talc and excess powder dusted off. The threads are then separated by a comb means and stretched by passing round concave forming rollers 30 and 32 and then between driven rollers 33 and 34.  The driven rollers exert the tension which causes the threads to stretch.  This operation exposes untalced areas of rubber, lays the threads down contiguously side-by-side and presses them together.  The product is a flat tape which is then vulcanized fully.  The component threads may be easily pulled from the ribbon without tearing.

Abstract: 1309977 Radar DNEPROPETROVSKY ORDENA TRUDOVOGO KRASNOGO ZNAMENI GOSUDARSTVENNY UNIVERSITET 300 LETIA VOSSOEDINENIA UKRAINY S ROSSIEI 16 July 1971 [23 July 1970] 33506/71 Heading H4D Parameters of an article are measured by comparing the phases of two microwave signals directed at two surfaces thereof with the energy reflected therefrom. The displacement of strip 1 is measured by radiating from aerial 4, microwave energy from source 1 via divider 2 and circulator 3. Reflected energy is directed by circulator 3 to phase comparator 5 where it is compared with a reference signal from divider 2 via phase compensator 6 and divider 7. The phase difference is detected by logic 11 and used to control compensator 6 to restore the normal phase relationship, the controlling voltage being detected by indicator 12 to show the displacement. The phase compensated signal from divider 7 is radiated on to the second surface of strip 1 via circulator 8 and aerial 9. The reflected energy is compared in phase to the source 1 output signal. Comparator 10 thus indicates the strip thickness independent of any displacement thereof. In apparatus for measuring the shape and thickness of moving sheet steel (Fig. 2, not shown) three pairs of aerials are provided across the sheet which continuously measure the displacement and thickness of the sheet. The phase differences are measured by radiating a first signal on to the first surface and phase modulating the reflected signal. This modulated signal is mixed with the phase compensated transmitted signal and detected before being passed to a logic unit which detects the phase error and alters the phase compensator as described previously. The phase compensated first transmitted signal is radiated on to the second surface and the reflected signal phase modulated and mixed with the output of the microwave source which has been phase compensated under the control of a phase comparator as above. The comparator output indicates thickness. A single modulating source is used for all three channels and a power divider provides the energy for all three channels from a single microwave source.
